Hadith 2:497

Narrated Abu Masud Al-Ansar:

Whenever Allah's Apostle (p.b.u.h) ordered us to give in charity, we
used to go to the market and work as porters and get a Mudd (a special
measure of grain) and then give it in charity. (Those were the days of
poverty) and to-day some of us have one hundred thousand.
